Always use the protection guards and your safety glasses, earwears and dust masks.
Use the diamond blades for the corresponding materials to cut. Problems below might arise if the wrong blades are used or wrongly operated.
------------------------------------------------------------------
Segment loss (Causes / Remedies)
• Blade too hard for material being cut / use proper blade specification for material being cut.
• Blade twisting or jamming in cut / keep sawing straight when the blade working (concave blade
exceptional)
• Out of round blade / replace worn bearing, realign blade shaft or replace worn blade arbor.
• Incorrect blade tension / ensure blade is running at correct RPM.
• Excessive cutting speed / slow down the cutting speed .
Blade worn out of round (Causes / Remedies)
• Incorrect mounting of blade / remount blade correctly.
• Worn bearings, spindle or blade arbor / replace worn bearing, realign blade shaft or replace worn
blade arbor.
• Blade too hard for material being cut / use proper blade specification for material being cut.
Blade arbor out of round (Causes / Remedies)
• Blade incorrectly seated / remount the blade correctly.
• Worn flanges or flanges not properly tightened / tighten flanges properly or replace worn flanges.
• Blade shaft worn / replace worn blade shaft.
Segment cracks (Causes / Remedies)
• Blade too hard for material being cut / use proper blade specification for material being cut.
Steel center cracks (Causes / Remedies)
• Excessive cutting pressures / slow down the cutting speed and keep correct feed rate.
• Incorrect blade tension / ensure blade is running at correct RPM.
• Jamming or twisting in cut / keep sawing straight when the blade working (concave blade exceptional)
• Blade too hard for material being cut / use proper blade specification for material being cut.
Slow cutting (Causes / Remedies)
• Blade becoming glazed due to use on material too hard for bond / To sharpen blade, make fast (3- 4m/min) shallow (3-10mm deep) passed in the material being cut, or in sandstone or asphalt for quicker results.
• Excessive cutting pressure, high shaft RPM, low machine HP or drive belts loose / tune engine according to manufacturer's manual.
Blade wobbles (Causes / Remedies)
• Incorrect mounting of blade / remount blade correctly.
• Worn bearings or bent shaft / replace worn bearing or blade shaft.
• Blade RPM too high or incorrect tension / ensure blade is running at correct RPM.
Uneven segment wear
• Check bearings and spindle for wear, machine alignment and equal water supply to both sides of blade.
